I got the B&W 3 ball hitch. What an incredible piece of hardware! I ordered the locking pin to help it to not grow legs. I really like it, had to pull car trailer with 2-5/16 ball, pull pin, rotate, and done. They are expensive, but pleased with the build quality.

20" wheels (not my favorite wheel, but its growing on me)

Update, no warranty on tires. Talked to Discount Tire they said "factory tires have no warranty". Called dealer, basically told same thing "sidewall damage not covered". Did put the Duratrac tires on, they work amazing in the snow and ice.

SilveradoX2, good to hear on the Duratracs. Trying one more time to load the pics, didnt catch the HEIC format, must be coming off iPhone that way... Bulge is right at the "A" in AT.

I am lost I guess, will try again to push a pic up.. Well the forum wont let me post any pics now, so I guess people can just keep an eye on their sidewalls, I will try to warranty the tire and see how that goes.

IMG_3562.HEICIMG_3561.HEICI noticed on my AT4 that the Trail Runner tires have developed a bulge in the sidewall. I am putting some Duratracs on the truck, and going to see if they will warranty the tire. Posting this so others can be on the lookout. IMG_3562.HEIC IMG_3561.HEIC IMG_3562.HEIC IMG_3561.HEIC

Thank you, does look like 8" drop is the ticket for a boat. The TailgateFix on Amazon link was helpful, it does seem pretty clean looking. B&W hitch now back in contention in my mind too, that was helpful In2racn, thank you.

I agree with you Ron, I also have a 2020 AT4, what I am wondering is if 6 inch drop is enough for my bass boat trailer... The truck seems to ride pretty high, I will do some measuring with my old hitch first. The B&W hitch will bang into the gate the first time you forget to fold it under. The lockout seems like it would work, but I don't care for the lack of information on how it hooks into the truck, etc... The other thing I would like is a 2.5" hitch that cleared. Small problem to have for such a great truck, I am sure better solutions will show up soon.

2020 AT4 2500, getting 21.0 MPG on the freeway running 75-76 MPH. Truck only has 1400 miles on it, so might get better? This is my first Diesel powered truck, and first GM. Love the truck so far, the power and the MPG exceed my expectations.

Thank you.

Beautiful setup. Did you get the wheels from Tire Rack? I want to get a set of winter tires / wheels and wondering if the tire pressure monitors are hard to sync up? I just picked up a white AT4 with the Duramax, love the truck.
